Construction early warning, acceptance evaluation, operation and maintenance, health monitoring, academic research, and more
Deformation monitoring of tunnel structures is an important means of ensuring tunnel safety. With high-precision monitoring technology, engineers can track the displacement, settlement, and deformation of the tunnel in real time to prevent potential hazards. The system typically adopts non-contact sensing technology, keeping the structure untouched while delivering continuous, reliable data.
Deformation monitoring of prefabricated metro stations uses high-precision trackers to monitor the station in real time during construction and operation, ensuring the safety and stability of the structure. For metro stations built with an internal support, large-block, fully prefabricated structure, continuous monitoring helps verify structural behavior at every stage.
Deformation monitoring of the high-speed rail pier section of the airport link is a key step in ensuring bridge safety. With high-precision equipment such as the flexible vision tracker, displacement, inclination, and deformation of the piers are monitored in real time without any contact with the structure. The equipment uses IoT technology to support remote access and automated long-term operation.
